Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8148, here are decompositions:

  • 31 + 8117 = 8148
  • 37 + 8111 = 8148
  • 47 + 8101 = 8148
  • 59 + 8089 = 8148
  • 61 + 8087 = 8148
  • 67 + 8081 = 8148
  • 79 + 8069 = 8148
  • 89 + 8059 = 8148

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8148 first appears in π at position 5,315 of the decimal expansion (the 5,315ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
